There are several "check_printer" plugins on the nagios exchange, it
may be helpful to detail which one you're referring to.

You're running this command using the sudo command.  This implies a
root execution, unless you failed to disclose information about the
sudo setup, and how you're executing it.  You should always attempt to
start the command as the user running the nagios daemon.

Guessing you're using the PHP version from ciphron.de, it requires php
with SNMP support.  You've already validated that it exists due to
being able to execute it under sudo, so the next thing would be a
quick sample script to validate, and get real errors.  The PHP script
has the errors masked, so it makes it harder to debug.  Use the
following as a sample:

#!/usr/bin/php
<?php
echo snmpget('printaddress','public','.1.3.6.1.2.1.43.11.1.1.8.1.1');
?>

Save as a script, make executable, and run as the user executing
nagios.  snmpget might be returning an error message in the script
that is being masked with the @ symbol.
